• Semester 6, position 3

Introducing to fundamentals of Electronics, the most common electron components and circuits. Presentation of the basic medical measurements and diagnostically methods. The focus is on the operation of standard biomedical equipment with brief description of device construction. The subject educates engineers to improve still existing and develop new biomedical devices.

By attending the course, students will be educated to understand and analyze problems concerned with operation and usage of basic biomedical instrumentation and equipment. This course educate students to connect basic principals of electronics, physics and medicine and to practically implement them into modern medical equipment.

Principles of Electrical engineering. Semiconductors and p-n junction, diodes. Bipolar transistors. Basic amplifiers with bipolar transistors. Operational amplifier, feed-back. Principles of medical measurements and instrumentations. Cell's electrical activity. Electrodes for biopotential measurements. Biomedical sensors. Principles of circulatory system and electrical properties of the human heart (cardiac muscle). EKG measurement, measurement of blood pressure, measurement of blood and gas flow. The measuring of the breath amount (volume) and breath speed (flow). The measuring of gas concentration. Muscles contraction, programmable electronic muscle stimulator.

Principles of Electrical engineering - exercise. Numerical examples - Semiconductors and p-n junction. Diodes behavior in electric circuit. Numerical examples - Bipolar transistors. Examples - Electric circuits with operational amplifier. Principles of medical measurements - methods. Measurement of blood pressure, measurement of blood and gas flow - examples.
